Description
Fahrzeug einzusteigen braucht.Vehicle needs to get in.
In der Zeichnung ist eine Ausführungsform der Erfindung dargestellt. Im einzelnen zeigtIn the drawing is an embodiment of the Invention shown. In detail shows
Fig. 1 die Seitenansicht einer auf einer Tragenführung aufruhenden und auf dieser arretierten Krankentrage, Fig. 1 is a side view of a stretcher guide resting and locked on this stretcher,
F i g. 2 eine Draufsicht zu F i g. 1,F i g. 2 is a plan view of FIG. 1,
F i g. 3 einen Ausschnitt aus der hinteren Arretiervorrichtung der Fig. 1, und zwar in Arretierstellung und in vergrößertem Maßstabe,F i g. 3 shows a section from the rear locking device of FIG. 1, specifically in the locked position and in enlarged scale,
Fig. 4 die gleiche Arretiervorrichtung wie Fig. 3, jedoch in Frelgabestellung und4 shows the same locking device as FIG. 3, but in the open position and
F i g. 5 eine Ansicht der hinteren Arretiervorrichtung von hinten.F i g. 5 is a rear view of the rear locking device.
Auf eine Tragenbühne oder Tragenführung 10 ist die Krankentrage 11 mittels ihrer an den Längsholmen 12 gelagerten vorderen Rollen 13 und hinteren Rollen 14 aufgesetzt. F i g. 1 bis 3 zeigt die Trage in arretierter Stellung. Zur Arretierung dienen einerseits die im Ausführungsbeispiel vorderen Unterfahrhaken 15, in deren nach hinten geöffnete Ausnehmungen die Achsen 16 der Rollen 13 in Pfeilrichtung -y von hinten her eingeschoben sind, bis sie an den Unterfahrhaken einen Anschlag finden.The stretcher 11 is on a stretcher platform or stretcher guide 10 by means of its on the longitudinal struts 12 mounted front rollers 13 and rear rollers 14. F i g. 1 to 3 show the stretcher in locked position Position. On the one hand, the under-run hooks 15, in the exemplary embodiment, are used for locking whose recesses open to the rear, the axes 16 of the rollers 13 in the direction of the arrow -y from behind are pushed in until they come to a stop on the under-run hooks.
Zur Arretierung der Krankentrage gegen ein Verschieben nach hinten dienen die schwenkbaren hakenartigen Arretierelemente 17, die auf einer Querwelle 18 angeordnet bzw. durch deren Enden gebildet werden und die Achsen 19 der hinteren Rollen 14 in Arretierstellung übergreifen und dadurch arretieren. Die Querwelle 18 ist in Lagern 20 gelagert, die — wie auch die Unterfahrhaken 16 — mit der Tragenaufl;..-ge 10 fest verbunden sind.The pivotable ones are used to lock the stretcher against shifting backwards hook-like locking elements 17, which are arranged on a transverse shaft 18 or through the ends thereof are formed and the axes 19 of the rear rollers 14 overlap in the locking position and thereby lock. The transverse shaft 18 is mounted in bearings 20, which - like the under-run hooks 16 - are connected to the stretcher support; ..- ge 10 are firmly connected.
Die hakenartigen Arretierelemente 17 sind aus der zurückgeschwenkten Lage nach F i g. 3 etwa um 90" in die hochgeschwenkte Lage mich Fig. 4 schwenkbar, und zwar mittels eines auf der Welle 18 befes'.igten Hebels 21, an den mittels Gelenkes 22 das z. B. in der Länge verstellbare Längsgestänge 23 angeschlossen isi. Diesem ist durch einen Handhebel 24 betätigbar, der in einem an der Tragenauflage angeordneten Lager 25 schwenkbar gelagert und mittels eines Hebelarmes 26 und Gelenkes 27 mit dem Längsgestänge 23 gelenkigThe hook-like locking elements 17 are from the pivoted-back position according to FIG. 3 around 90 "in the swiveled up position can be swiveled in Fig. 4, namely by means of a lever 21 fastened on the shaft 18 to which the z. B. in the Length adjustable longitudinal rods 23 connected isi. This can be actuated by a hand lever 24, which is shown in a bearing 25 arranged on the stretcher support and pivotably mounted by means of a lever arm 26 and joint 27 with the longitudinal rod 23 articulated
ίο verbunden ist.ίο is connected.
Durch Verschwenken des Handhebels 24 in Pfeilrichtung x\, z. B. um etwa 180°, können die hakenförmigen Arretierelemente 17 aus der Freigabestellung nach Fig. 4 in die Arretierstellung nach Fig. 3 geschwenkt werden. Durch Bewegung in umgekehrter Richtung in Pfeilrichtung x? erfolgt die Freigabe der Krankentrage, die hierauf nach hinten entgegen der Pfeilrichtung χ von der Tragenauflage, z. B. aus dem Fahrzeug, entfernt werden kann.By pivoting the hand lever 24 in the direction of the arrow x \, z. B. by about 180 °, the hook-shaped locking elements 17 can be pivoted from the release position according to FIG. 4 into the locking position according to FIG. By moving in the opposite direction in the direction of the arrow x? the stretcher is released, which then moves backwards against the direction of the arrow χ from the stretcher support, e.g. B. from the vehicle can be removed.
Wie ersichtlich, führt der Handhebel 24 aus der einen in die andere Endstellung eine Schwenkbewegung aus, bei der der Gelenkpunkt 27 eine Tolpunktstellung mit Bezug auf eine Gerade überschreitet, welche das Gelenk 22 mit dem Lagerpunkt 28 des Handhebels 24As can be seen, the hand lever 24 performs a pivoting movement from one end position to the other, at which the articulation point 27 exceeds a tol point position with reference to a straight line which the Joint 22 with the bearing point 28 of the hand lever 24
-'5 verbindet. Bei einem Druck der Krankentrage nach hinten entgegen der Pfeilrichtung ν auf die hakenförmigen Arretierelemente 17 wird infolgedessen der Handhebel nur noch stärker in Arretierstellung gedrückt, so daß eine ungewollte Freigabe der Trage-'5 connects. When the stretcher is pressed backwards against the direction of the arrow ν on the hook-shaped As a result, locking elements 17 make the hand lever only stronger in the locked position pressed, so that an unintentional release of the stretcher
jo verhindert wird. Die Arretierlage des Hebels 24 kann hierbei durch einen Anschlag bestimmt sein, der /.. B. dadurch gebildet wird, daß der Hebelarm 26 an die Tragenauflage 10 anschlägt.jo is prevented. The locking position of the lever 24 can be determined by a stop which / .. B. is formed in that the lever arm 26 strikes the stretcher support 10.
